Patented Sept. 29, 1931 UNITED STATES LEOPOLD LASSELSBERGER, OF NIEDERNDORF, AUSTRIA DISENGAGEABLE- COUPLING DEVICE Application filed March 28, 1930, Serial No. 439,803, and in Austria April 3, 1929. Renewed June 19, 1931.

disengaged from the other element.

According to the present invention on the releasable element a single tubular member or a member substantially surrounding such element, such as a sleeve is slidably mounted,

so that by longitudinally moving said sleeve inwards said element is freed and can be lrawn out and cleared trom the other element. Such an arrangement which enables a. ready and reliable disengagement oil'ers no Moreover the releasing means is easily operable and has a simple and nonexpensive structure.

ln the drawings:

Fig. l shows an embodiment ot the invenl l' tion illustrated perspectively by way of eX- ample. Figs. 2, 3, and l show modifications in cross sectional views and in perspective view respectively. The element z' of the coupling is capable of being inserted in the secll ond element g thereof. The latter contains springs or spring urged members a, b, which in case the element i is introduced in the element g are spread apart from each other F and linally engage the element i in such manner that the two elements z' and g are coupled together.

For enabling the two elements to be separated a tubular member or a sleeve 71 is slidably arranged on the element a'. Said sleeve 7a may be moved longitudinally into the element g and between the members-o, Z), so that said members are shifted outwards and disengaged from the element t' or from an fc3 enlargement or head of the same as shown in Fig. l. The element being freed may be drawn out.

The particular forms of the invention illustrated in the drawings are not to be taken as limiting it, but are intended to be illustrative of various manners of embodying and carrying it out.

l rl"he coupling device may be given any den sired cross sectional shape for example a circular one (Fig. 2), or the tubular member /L may be formed by a strip of material bent completely or partially around the element z' as shown in Fig. 3.

rlhe member h may be a sleeve 7L (Fig. 4) having one or two prongs L the latter serving to free the element z' or to spread the springs a, b apart from each other.

instead of two springs, or two spring urged members or pawls only one may be sufficient in some cases.

l/Vhat I claim is: i

ln a disengageable coupling device compris-mg two elements, spring urged means Jfor holding the two elements in engaged position and a member being slidably mounted on one element for releasing said holding means by merely longitudinal motion of said member, said means comprising two springs in the other element which may be spread apart from each other by said member for the purpose of disengaging the two elements.

ln witness whereof I alix my signature.
